Frodo now a picture of health

The koala joey has put on a fifth of her body weight in a little over a month since she was found riddled with lead pellets and lying next to her dead mother on a road near Jimna, in the Sunshine Coast hinterland.

While the koala's recovery has amazed vets at Australia Zoo's Wildlife Hospital, police have not made much progress in finding the koala killer.

Stock and Rural Crimes Squad senior constable Brad Johannesen said police had followed up information that had come through from Crime Stoppers, but there had been no arrests.

“At this point it has all sort of dried up,” senior constable Johannesen said.

“We're still hoping someone else will come forward with information. We are sure someone knows something, they just need to tell us.”

The Wildlife Hospital's Dr Amber Gillett said she was very happy with Frodo's progress. She now weighs a healthy 2.36kg.

“Since being in care at the Australia Zoo Wildlife Hospital she has gained 400 grams, which is a great indicator of how well she is doing,” Dr Gillett said.

The lead pellets still lodged in Frodo's body do not appear to be affecting her health, but Frodo still has a long way to go before being released back into the wild.

“Lead toxicity from some of the pellets remaining in her intestinal tract will still be monitored,” Dr Gillett said.

“The pellets in her stomach and intestines seem to be moving around but have not been expelled, and may never be.”

Frodo's fur has also started to grow back over her wounds and no further surgery has been scheduled.

She will have another thorough check-up after Christmas to reassess the lead levels.

Anyone with more information about the attack should contact Crime Stoppers on 1800 333 000.
